Structural roles of PCV2 capsid protein N-terminus in PCV2 particle assembly and identification of PCV2 type-specific neutralizing epitope
Fig 1
Crystal structure of PCV2-His-ΔN45 VLPs.
(A) Ribbon representation of crystal structure of PCV2-His-ΔN45 VLP at 2.8Å assembled from 60 PCV2 capsid protein subunits. (B) The association of subunits in dimer, trimer and pentamer form, presented from VLPs. (C) Structural comparison of crystal structure of PCV2-His-ΔN45 subunit and cryo-EM structure of full-length PCV2 subunit. The crystal structure of PCV2-His-ΔN45 subunit is colored in light yellow, whereas the cryo-EM structure of full-length PCV2 subunit is colored in light blue.
